Patent DE-2349732-A1 (DE)
Title: Continuous assembly of girder beam - uses compensating loop of zigzag strut to coordinate bending and welding process
Inventor: KELLER KLAUS DIPL ING
IPC: B21F27/20
Filed: 1973-10-03
Abstract: A horizontal frame carries two sets of electrodes which are used to weld the upper and the lower straight member of the girder to the continuous zigzag strut. A slide next to the welding station carries the finished girder until it reaches its required length. Two tracks of endless roller chains are located in a frame. Each track has a number of bending elements attached which overlap between the identical elements on the opposite track. When a straight wire is passed between the tracks, a continuous zigzag ribbon is formed. This ribbon enters the welding station in such a way that a free loop which acts as a buffer is maintained. It is thus possible to coordinate intermittent welding with continuous bending.

Title: Flame monitor for self igniting burner - has opening time proportional to the electrical voltage on a condenser
Inventor: LEISENBERG WOLFGANG DIPL ING
IPC: F23N5/24
Filed: 1973-11-14
Abstract: Flames in self-igniting burners with discontinuous fuel supply are monitored by generating a signal proportional to or otherwise connected with the duration of opening a closure member in the fuel supply line. When a pre-set, adjustable value is reached corresponding to the max. permissible duration of opening, a control signal for the closure member is generated. Operation is reliable. The opening time is proportional to the electrical voltage on a condenser, and is in response to an analogue rectangular impulse, summed by an integrator consisting of a transistor and a thyristor, the switching being performed by a relay and a contact.

Title: Energy saving vehicle transmission - with electric motors and flywheel to store braking energy
Inventor: KOERNER HELMUT
IPC: B60L50/30
Filed: 1974-07-30
Abstract: The engine of the vehicle drives the transmission via an epicyclic gear box (4, 5) and a differential (9) on the back axle. An electric motor/generator (2) is driven by a coupling to the gear box to drive a flywheel (11) up to a fast speed to store energy. A similar electric motor/generator (3) on the back axle operates as a brake for regenerative braking to drive the first electric motor and store the energy in the flywheel. A control (12) regulates the functions of the two motors/generators. The flywheel can be set rotating while the vehicle is stationary so that added torque is available for starting. The flywheel drives the first motor/generator to generate current to drive the motor/generator (3) on the rear axle differential.

Title: Remote controlled hydraulic circuit for elastic throttle - has check valve which can be opened for reverse flow
Inventor: HEIDE BRUNO DIPL ING DR
IPC: F16K31/12
Filed: 1974-09-13
Abstract: A hydraulic circuit which controls an elastic throttle element (10) has a gear pump (2) which is fed from an oil reservoir (1). A three way solenoid valve (4) either returns the flow to the reservoir, or to a four way solenoid valve (7).

Title: Pulse controlled DC converter - transformer in series circuit has thyristors controlled by trigger signals from oscillator circuits
Inventor: HEINICKE HARALD
IPC: H02M3/137
Filed: 1974-09-30
Abstract: A D.C. voltage converter for supply of voltage to an inductive load is based upon pulse control of a transformer. The supply voltage applied to input terminals is transmitted over a series circuit to a transformer to output terminals coupled across the load. Pulse operation of the transformer follows over thyristors that receive trigger signals generated by a control circuit. For generation of the signals for the main thyristor and cancel thyristor, a square wave generator operating into a frequency divider produces signals that may be duration shaped to the required value. The series thyristor is controlled by saw tooth waveform generator operating into a pulse shaper. The third section of the control circuit directs the final thyristor through the saw tooth waveform generator and memory stage.

Title: Room air ioniser combined with radio aerial - has multiple cascade circuit producing high tension for field electrode
Inventor: SAX HERBERT
IPC: H01T23/00
Filed: 1974-11-09
Abstract: A multiple cascade circuit high tension generator (1) is connected at its high tension side with a projecting electrode (2). It is fed from a low tension supply (3) through a switch (4) and the potential gradient between the electrode and earth on the supply side produces an electrostatic field (5).

The low tension supply is also connected to a radio set. The multiple cascade high tension circuit causes no interference to the radio set and the circuit gives visual indication of the working of the ionisation equipment.

Title: Vehicle pneumatic tyre is adapted to keep running if punctured - by fitting rubber elastic support elements on the inside wall which prevent total collapse
Inventor: LUEDERS ALBRECHT DR ING
IPC: B60C17/00
Filed: 1975-05-13
Abstract: A vehicle pneumatic tyre suitable for running in emergency conditions e.g. after it has burst ("blown-out"), has at its inner side, several rubber-elastic supporting elements. Specifically, there may be, at both tyre sidewalls, supporting elements of equal size, fitted in such a way that they bear on the inner sides of the tyre base when the tyre is under extreme load in the event of loss of air from the tyre. The supporting elements do not form tyre components shaped integrally during mfr. of the tyre but may be subsequently fitted to any ordinary tyre. As a result, any tyre may be converted into a "safety" tyre.
